CAD, or Computer-Aided Design, is the use of specialized software to create, modify, and analyze digital designs and technical drawings in 2D or 3D, replacing manual drafting with a digital process. This technology streamlines the product development process by allowing for rapid prototyping, design exploration, simulation of real-world scenarios, and collaboration among designers, engineers, and manufacturers. CAD is a fundamental tool in many industries, including mechanical design, architecture, electronics, and product development, and often includes functionalities for computer-aided manufacturing (CAM).

Key aspects of CAD:

Digital Design: CAD software uses mathematical algorithms to create and display accurate 2D and 3D models of objects and structures on a computer screen.

Design Flexibility: It allows designers to quickly iterate on designs, explore different alternatives, and make modifications without the need for numerous physical prototypes.

Visualization: Users can manipulate and view designs from various perspectives, enabling detailed visualization and even photorealistic rendering.

Analysis & Simulation: Many CAD packages include tools for performing engineering analyses, such as structural or fluid dynamics simulations, to validate designs.

Collaboration: Cloud-based CAD solutions facilitate real-time, multi-user collaboration on projects, ensuring that all stakeholders are aligned on the design.

Manufacturing Integration (CAM): CAD data can be fed directly into Computer-Aided Manufacturing (CAM) systems to generate tool paths and plan fabrication processes.
